The required accompanying drawing used is briefly described in technology description, it should be apparent that, drawings in the following description are only this hair
Some bright embodiments, for those of ordinary skill in the art, on the premise of not paying creative work, can be with root
Other accompanying drawings are obtained according to these accompanying drawings.
The flow chart for the method that Fig. 1 is interacted by the digital instrument that the embodiment of the present invention provides with vehicle device navigation end；
The structured flowchart for the system that Fig. 2 is interacted by the digital instrument that the embodiment of the present invention provides with vehicle device navigation end.
Embodiment
The core of the present invention is to provide the method and system that a kind of digital instrument interacts with vehicle device navigation end, realizes digital instrument
Table interacts with engine end navigation, while ensures the stability of digital instrument, lifts the security of driving.
In order that those skilled in the art more fully understand the present invention program, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.Obviously, described embodiment is only part of the embodiment of the present invention, rather than
Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, belongs to the scope of protection of the invention.
It refer to Fig. 1, the stream for the method that Fig. 1 is interacted by the digital instrument that the embodiment of the present invention provides with vehicle device navigation end
Cheng Tu, comprise the following steps：
Step 101：Digital instrument CPU is interacted with digital instrument MCU and communicated, and digital instrument MCU will be gathered and handled
Vehicle traveling essential information be sent to digital instrument CPU.
Vehicle traveling essential information can include speed, engine speed, water temperature, oil consumption, mileage, car internal and external temperature,
Signal lamp and alarm lamp etc., these information are that some required information are driven in addition to information of road surface, such as driver
Need to know the consumption of fuel oil, so as to timely supplement fuel oil for automobile, avoid to travel because fuel oil is lacked
Situation occur.
Digital instrument MCU can use CAN to gather the essential information that above-mentioned vehicle travels, due to this collected
A little information are original information, it is therefore desirable to are then forwarded to digital instrument CPU after corresponding processing is done to it.
It can be interacted and communicated using UART serial ports between digital instrument CPU and digital instrument MCU, digital instrument MCU
The essential information of above-mentioned collection and treated vehicle traveling is sent to digital instrument CPU, and digital instrument CPU is to digital instrument
MCU sends the instruction that digital instrument HMI is issued.
Certainly it can also be interacted and communicated using SPI protocol between digital instrument CPU and digital instrument MCU, using what
Kind communication mode can't influence the realization of the present invention.
Step 102：Digital instrument CPU is interacted with vehicle device navigation end CPU and communicated, and vehicle device navigation end CPU leads vehicle device
The information at boat end is sent to digital instrument CPU.
The information at vehicle device navigation end can include radio reception machine information, Bluetooth information, navigation information, multimedia messages etc., this
A little information are not that the moment is indispensable, for example navigation information only uses when user does not know Road, without carrying out constantly
Navigation.
I can be used between digital instrument CPU and vehicle device navigation end CPU2C agreements interact communication, vehicle device navigation end
CPU hosted, digital instrument CPU do slave, and vehicle device navigation end CPU sends the letter at above-mentioned vehicle device navigation end to digital instrument CPU
Breath, and the instruction that digital instrument CPU issues to vehicle device navigation end CPU transmissions digital instrument HMI.
It can also be interacted and communicated using SPI protocol between digital instrument CPU and vehicle device navigation end CPU, be still car
Machine navigation end CPU hosted, digital instrument CPU do slave.The transmission speed ratio that communication is interacted using SPI protocol is used
I2The transmission speed that C agreements interact communication is fast, but uses I2C agreements interact communication, and device drives write ratio
It is relatively simple, it can be selected as needed in actual applications.
Certainly, between digital instrument CPU and vehicle device navigation end CPU Socket or serial communication or CAN can also be used total
Line or FPD-Link III universal serial bus interact communication, which kind of communication mode can't influence the realization of the present invention using.
Step 103：The information at essential information and/or vehicle device the navigation end that digital instrument CPU travels the vehicle received
It is sent to digital instrument middleware.
The essential information of vehicle traveling is required for transmitting always, and not necessarily the moment is all passing the information at vehicle device navigation end
Send, for example information can not just be transmitted when vehicle device navigation end is closed.
Step 104：The letter at essential information and/or vehicle device the navigation end that digital instrument middleware travels the vehicle received
Breath is sent to digital instrument HMI after being handled and shown.
Digital instrument middleware will be to letter after the information of the essential information of vehicle traveling and/or vehicle device navigation end is received
Breath does corresponding logical process, the state for making it be transformed to show on digital instrument HMI, is subsequently transmitted to numeral
Instrument HMI, digital instrument HMI come out these presentation of information.
The execution sequence of step 101 and step 102 does not influence the realization of the present invention, can perform simultaneously, can also be according to
Tandem performs.
In technical scheme disclosed in the present application, during being interacted at vehicle device navigation end with digital instrument, independent of number
The forwarding of word instrument single-chip microcomputer so that digital instrument single-chip microcomputer is only responsible for the processing of the essential information of vehicle traveling, reduces it
Workload, so as to reduce the risk that it goes wrong, ensure that the stability of digital instrument, and digital instrument middleware
Each performs its own functions with digital instrument HMI, and digital instrument middleware is responsible for the processing of information, and digital instrument HMI is responsible for the display of information,
This avoid the generation of this case that different operating logical miss, the stability of digital instrument is further increased；Realize
After digital instrument interacts with engine end navigation, the information at essential information and vehicle device the navigation end of vehicle can together be shown in numeral
In instrument, user avoids the need for diverting sb.'s attention on a large scale, improves the security of driving, while ensure that the steady of digital instrument
It is qualitative, the probability that digital instrument goes wrong is reduced, is also advantageous for safeguarding the safety driven.
Come below with the flow for checking vehicle device navigation client information of certain user in certain concrete application scene to disclosure
Above-mentioned technical characteristic be illustrated：
1) user digital instrument place selection check navigation information, digital instrument HMI issues dependent instruction, the instruction according to
It is secondary to send vehicle device navigation end CPU to via digital instrument middleware, digital instrument CPU；
